Note

This flow is only available for special case configured subscribers.

A subscriber must accept a quote before the firm window closes (ExpireTime, 126) to have a high probability of execution.

OpenYield ignores QuoteResponse (35=AJ) messages unless QuoteRespType (694) is 1 (Hit/Lift) or 6 (Pass). For a Hit/Lift, OpenYield takes the details from the forwarded quote and places a contra limit order on the marketplace.

For example, to accept the first quote from Quotes Forwarded to the Initiator (QRS20250214-SD-000000000001), send before the window closes:

8=FIX.4.4 9=238 35=AJ 34=452 49=BASTION-RQ 52=20250214-21:14:57.565 56=OPENYIELD-RQ 11=XORD-000001 22=4 48=US023135CF19 54=2 55=US023135CF19 117=QRS20250214-SD-000000000001 133=96.2832 135=100 453=2 448=Bastion 452=3 448=OYLD 452=1 693=XRES-000001 694=1 10=137

OpenYield acknowledges this as a new order (ExecType 150=0, OrdStatus 39=0) and places it on the order book:

8=FIX.4.4 9=326 35=8 34=458 49=OPENYIELD-RQ 52=20250214-21:14:57.586 56=BASTION-RQ 6=0 11=XORD-000001 14=0 17=RSP20250214-OD-000000000102 22=4 31=0 32=0 37=ORD20250214-OD-000000000028 38=100 39=0 44=0 48=US023135CF19 54=2 55=US023135CF19 118=0 136=0 150=0 151=100 157=0 159=0 236=0 381=0 453=3 448=Bastion 452=3 448=BAST 452=4 448=OYLD 452=1 10=243

The execution happens at the best price on the book, up to the price you send. In this case QRS20250214-SD-000000000002 (96.3399) was at the top of the book, so you are filled there, at a better price:

8=FIX.4.4 9=437 35=8 34=459 49=OPENYIELD-RQ 52=20250214-21:14:57.602 56=BASTION-RQ 6=96.3399 11=XORD-000001 14=100 17=FIL20250214-000000000002 22=4 31=96.3399 32=100 37=ORD20250214-OD-000000000028 38=100 39=2 44=96.3399 48=US023135CF19 54=2 55=US023135CF19 60=20250214-21:14:57 64=20250218 118=97485.73 136=0 150=F 151=0 157=86 159=1145.83 236=5.11492046 381=96339.9 453=5 448=Bastion 452=3 448=OYLD 452=17 448=0235 452=18 448=BAST 452=4 448=OYLD 452=1 10=223
